Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529036, here are decompositions:

43 + 31528993 = 31529036
67 + 31528969 = 31529036
127 + 31528909 = 31529036
193 + 31528843 = 31529036
223 + 31528813 = 31529036
229 + 31528807 = 31529036
307 + 31528729 = 31529036
313 + 31528723 = 31529036

Showing the first eight; more decompositions exist.
